说明：  MATLAB 前推回代法的配电网的潮流计算程序，适合于辐射性配电网和少环的配电网(MATLAB forward and backward substitution method of distribution network load flow calculation program, suitable for distribution network and less radiation distribution network ring)

对有类别监督的数据进行先行判别分析用于降维 数据为结构体类型，返回数据也是降维后的结构体类型。如(a.X a.y)a.X是带有类别的数据，a.y是类别信息(Synopsis: model = lda(data) model = lda(data,new_dim) Description: This function is implementation of Linear Discriminant Analysis. The goal is to train the linear transform which maximizes ratio between between-class and within-class scatter matrix of projected data.)

用Simulink中NCO模块产生正弦信号的程序，自己写的，采样率180MHz，正弦频率70MHz，可以直接运行。(Using Simulink module generates a sinusoidal signal of NCO program, sample rate 180MHz, sinusoidal frequency 70MHz, can be directly run.)

信道仿真,小尺度衰落信道的MATLAB仿真源码（jakes仿真模型）(Channel simulation, small-scale fading channel MATLAB simulation source (jakes simulation model))

For a thorough description of the norms, see the Chapter 4 of Robust and Optimal Control, Zhou, Glover, Doyle 1996. Here the point is to give some lines of code illustrating what are the H2 and Hinf norms of LTI systems. In that sense, it is also illustrated that the H2 norm is smooth in the space of the system parameters, whereas the Hinf norm is non-smooth locally Lipschitz (since it is a min-max problem, thus prone to the waterbed effect ).
